Laser Imaging is a powerful tool for Multi-Parameter Flow Imaging.
LaVision combines, in a unique way, flow velocity imaging based on Particle Image Velocimetry (PIV) with imaging of scalar flow parameters such as concentration, mixture fraction and temperature applying Laser Induced Fluorescence (LIF), Rayleigh and Raman techniques.
High resolution droplet sizing and particle imaging are accomplished using Interferometric Mie Imaging (IMI) and Shadow imaging, respectively. In addition, particle concentration fields are recorded using Mie scattering or Laser Induced Incandescence (LII). Laser Imaging builds up a complete framework of imaging techniques with complementary information about the flow field (see Multi-Parameter Laser Imaging Matrix below).
Combination of imaging techniques captures additional flow features like:
